Abstract Nitrate (NO 3−) pollution in water and wastewater has become a serious global
issue. Biological denitrification, which reduces NO 3− to N 2 (nitrogen gas) by denitrifying …

Transforming organic waste into stable carbon by composting is an eco-friendly way.
However, the complex environment, huge microbial community and complicated metabolic …

This study explored the response of NO3–-N bioreduction to Cr (VI) stress, including
reduction efficiency and the pathways involved (denitrification and dissimilatory nitrate …

No consensus has been achieved among researchers on the effect of dissolved oxygen
(DO) on nitrate (NO 3−-N) transformation and the microbial community, especially during …

With continuous economic and technological growth, sustainable development must be
pursued and comprehensive transformation of economic and social development systems …

Polycyclic aromatic hydrocarbons (PAHs) are a class of hazardous organic contaminants
that are widely distributed in nature, and many of them are potentially toxic to humans and …

Aromatic compounds (ACs) releases aroused by sediment resuspension would certainly
change the concentrations of suspended sediment (SPS) and organic carbon, which may …

Both potentially toxic elements (PTEs) and polycyclic aromatic hydrocarbons (PAHs) are
widely present in soil contaminated by steel industries. This study assessed the vertical …

The aim of this study was to understand the role of indigenous soil microbial communities on
the biodegradation of polycyclic aromatic hydrocarbons (PAHs) and to determine whether …

Soil microbes play important roles in plant growth and in the biogeochemical cycling of
earth's elements. However, the structure and functions of the microbial community …
